GENMA Maintenance Tip | How to Choose the Right Grease?

Not all greases are created equal – prices range from cheap to crazy expensive. But here’s the truth: the most expensive grease isn’t always the best. The right match matters way more.

 GENMA’s go-to grease

For most lubrication points on GENMA equipment, we recommend GADUS S2 V220 2 – a high-performance lithium-based grease that handles wide temperatures, resists wear, and fights corrosion and oxidation.

Just to be clear: GADUS S2 V220 2 is a performance reference, not a fixed rule. When choosing grease, ambient temperature is your first consideration.

This grade works well in temperatures from -20°C to +130°C, which covers most temperate and subtropical regions.

• Below -20°C (extreme cold)? Go with a softer NLGI 1 or 0 grease for better pumpability.

• High-temperature conditions? Choose a high-temperature synthetic grease.

For extreme hot or cold environments, contact your GENMA service engineer for specific recommendations.

Why you shouldn’t just grab any grease

Different greases have very different thickness (consistency), drop points, and pressure performance. Using the wrong one can cause:

• Too thin → melts away under heat → no lubrication

• Too thick → won’t pump in cold weather → clogs your central lube system

• Incompatible base oil → grease hardens or separates → total failure

3 simple rules for picking grease

1. Brand & spec – Stick with GENMA-recommended types when possible.

2. Ambient temperature – Choose the right NLGI grade (e.g., NLGI 2 works for most temperate regions).

3. Application – Heavy loads & low speeds = extreme-pressure grease. High speed & light loads = standard grease.

Yes, grease expires too

It doesn’t last forever. Stop using it if you see:

• Dark or black color

• Oil separating on top

• Hard, crusty chunks

• White, milky look (water contamination)

• Sour or rotten smell

Expired grease doesn’t just fail – it can speed up wear.
